I think im a demigod...please help?

Okay,so I always have a feeling that someone is watching me or following me.And when im listening to music,nothing seems to go wrong,my reflexes are always better,and everything seems to move slower and i see alot more than usual(sometimes i see to much)and im always having da-ja-vu...and i can always know what is going to happen in like the next 5 hours.....and i live with my mom(im only 13) and i know who my dad is,but i look absolutly nothing like him.....my mom is always telling me lies......and i've been attacked by people many times....and im very skilled at swordmanship,and archery....and dont say it sounds like parinoia or something...and do not say i have a wild imagination...im telling the truth....
